Questions about or involving outside the range of normal machine precision, using Mathematica's capacity for arbitrary precision numbers and numbers outside the normal range of floating-point arithmetic.

I used Wolfram Alpha to find the sum of digits of these large numbers but the results are " standard computation time exceeded ". Could you help me because I want investigate these four numbers:
$((...

I generally prefer to do all my intermediate calculations with exact numbers, and then round my result at the end. Thus I will typically convert each arbitrary-precision number to its exact equivalent;...

How to solve a complex equation of the form:
$$z^n \equiv i \pmod p$$
where $z$ is a Gaussian integer, $i$ is the imaginary number, $n, p \in \mathbb{Z}^+$ and $p$ is prime.
I am dealing with quite ...

What is the number of digits (IntegerLength) of the factorial of 12 345 678 987 654 321? The number of zeros at the end of this factorial was calculated and it is huge: exactly 3 086 419 746 913 569 ...

I am going to be working with very large numbers, and would like write the input in the base 10 and have the computer output in another arbitrary base. If it truly is limitless, that would be awesome ...

I've been working on this all night, and I have made this go pretty fast, compared to my first iteration of the program, but now I'm out of ideas.
I'm trying to write a program to test (by good old ...

I am exporting some data into the txt file but since the values exported to this txt file
expresses 10^6 to be *^6, I cannot use these numbers in calculations in other programs..
For instance, when I ...

I'm using "mathlink.h" to call Mathematica from a C program. I send a computation to Mathematica and its return result is a very big number (100 digits). Hence, I want to read that number as a string.
...

I want to improve timing of squaring for big numbers.
So I asked What is the fastest way to split a number into parts and What is the most efficient way to add zeros to end of a number with several ...
